rmcn or eminence moan raarrcurmr .ADAPTED roa rmme acamsr Am- Application filed October 25, 1926, Serial No. 144,068, and France December 10, 1985.

This invention relates to a iece of ordnance iy zarticularly adapted to ring against aircra In my prior application Serial No. 72,743,

I filed December 2, 1925, there are described and illustrated various forms of construction of a piece of ordnance more particularly adapted for firing against aircraft. The

main feature of this piece of ordnance is i 1 that the cradle is journalled at its rear end in bearings provided upon a platform which is movable about a pivot, the whole of the oscillating mass being su ported on account of the fact that the crad e is connected, at a point near the centre of gravity of the said signed that for any angle of inclination of the oscillating mass, balance is practically obtained.

This invention relates to a form of this gun characterized by an arrangement which greatly facilitates the operations necessary for mounting the gun for transport purposes by means of a limber and hind carriage, use

being made of the general features recalled above. f

The new constructional form of the is essentially characterised by the fact that the platform is constructed in the form of a top so carria e adapted to turn in a saddle itself movab e, by means of a knee joint, in apedestal carried by three arms two of which are pivotally mounted so as to be adapted to open out fan wise in order to be anchored 85 to the ground while thethird is integrally secured to the pedestal and may be provided at its free end, with an operating lever.

The gun thus constructed is combined, for the purposes of transport, with a hind car- 4 riage forming a supporting cradle for the gun and adapted to be placed beneath the arm integrally secured to the pedestal 1n order to slide this arm into the cradle on the axle of the carriage when the gun has 16. been raised by means of the said lever. On

account of the principle of constructionv ado ted for the gun the latter may be raised in t is we without effort, support being taken for t e gun upon theends of the two pivotally connected arms. Then, the arm integrally pedestal being fitted into the axle of the hind mass to a counterbalancing device so deing the gun. for the pedestal into the secured to the carriage, the pivotal arms which are connected to-each other may be raised after the gun has been rotated towards the rear carriage in order to assist in performing this raising operation.

An .example of the gun thus designed is illustrated in the accompanying dra Figure 1 is a longitudinal elevation. o the gun in battery position. F'gure 2 is a corresponding plan. iFigure 3 is a cross-sectional elevation to a larger Fig. 1, looking from left to right, with portions conveniently cutaway to allow the cylinder I and the pivot to be seen in section.

Figure 4 illustrates the operation of raispurpose of fitting the secured to the gun carriage supporting cradle upon the axle of the rear carriage.

Figure 5 shows the diflerent operations to be carried out in order to bring the oscillating mass into the position which will enable arm integrally the whole of the apparatus to be swungbg taking support upon the axle of the carriage.

Figures 6 and 7 show in elevation and plan respectively the position occupied by the gun when mounted for travelling.

Fi re 8 is a side elevation illustrating one orm of carriage for supporting the gun and mounting.

The gun comprises a cradle B which is journalled at its rear end 6 in bearings d, d carried upon a support D which is movable about a pivot. The oscillating mass is wholly supported on account of the fact that the said cradle 13 is connected at a point B near the centre of gravity of the said mass, to a spring counterbalancing device I-K so chosen that for any angle of incliscale taken along the line 3-3.in.

nation of the said mass balance is practically obtained. p

The form of construction according to the present invention is essentially characterized y the 'feature that the support is con a co joint in a pedestal D This pedestal may be anchored to the ground .by means of arms.- According to the invention. two of -the three anohorin (D, D) are'pivotally connected to t e said pedestal while the third D is. integrally secured to the said pedestal and is arranged so as to receive atits free end an operating lever E. The thus constructed is combined, for the purposes of transport by road, with a hind carriage the axle G of which forms a supporting and securing cradle for the arm D as shown clearly 1nvv Figure 8 which is a cross-sectional elevation of the hind carriage showing the gun in position for transport.

When it is desired to transport the gun, constructed for firing as shown in Figure 1.

, the anchoring trail-spade is withdrawn and the operating lever E is fitted into the arm D. Care is naturally taken to bring the oscillating mass into the position shown in Figure 1, which position is nearly-horizontal and ractically in alignment or in alignmentw1th the arm D..- On account of the position of the centre of gravity of the oscillating mass it. is extremely easy to raise the gun by means of the lever E, sup ort being taken upon the ground by the anc oring platform formed by the two arms D, and this raising of the gunfimay be efiected without a great force being exerted.

When the is raised into the position shown in Flgure 4 the hind carriage is placed beneath the lever, first in the position shown in dot and dash lines in Figures 4 and 2, then the hind carriage is turned in order to bri-n it into the position shown in full lines in t e same figures, which enables,

- ate the elevating by suitably plac gthe arm D, the latter to be,fitte upon t e axle G.

When this is done, the oscillating mass is brou ht into the position shown in dot and das lines in Figure 5; to this end the said mass 'is righted by means of the vertical elevating mechanism which brings thecentre of avity of this mass near the axis of 'the pivot; then the mass is turned through 180 by means of the training mechanism. Then, still continuing to actumechanism, the oscillating mass 1s lowere ipto a position which. 'is practically symmetrical with the one it occupled at the commencement of the operat1on and which is also shown in dot'and dash lmes in Figure *5, p The lowering pf the whole of the gun, by pivoting about the axis of the axle G, is then' a very simple matter the centre of gravity of the arrangement being in the nelghbourhood of the-vertical line passing through the axis of the said axle. The two pivotally connected arms D arethen drawn 0 ther in order that they may be connecttogether at their ends, as'shown in-Fig- ,ure 7, by means of apintle eye to a limber of known construction.
